Using the Flow-Clik Interface Box, the sensor is calibrated by pressing the Calibrate button while the highest flow zone is operating. While the system is learning the flow, the System Status Indicator light will be yellow. After a 10 second period of learning it will begin to monitor system flow.
Note: Before calibrating the Flow-Clik to your system, it is very important that the irrigation system be in good working condition. Irrigation system leaks, broken sprinklers, zones operating outside specified pressure ranges, will have a negative effect on the performance of the Flow-Clik.
You can also use your controller to help calibrate the Flow-Clik in a system with unknown flow rates among zones. This method is easy, accurate and prevents the user from having to count and estimate system zone flows. Simply operate your controller manually and sequentially “learn” as you cycle through each of the zones.
Note: If your controller is programmed to operate more than one zone at a time, those zones will have to be activated together to calibrate the Flow-Clik to total system flow.
